SPINDLE OF COTTON AND THE LIKE SPINNING MACHINES.

Application filed .Tune 12,

To all whom it may concern:

Be it known that I, Fnnonnion HoRroN CLoUeH, a subject of the British Empire, residing at Hillmorton, near Rugby, England, have invented certain new and useful Improvements in and Relatin to the Spindles of Cotton and the like bpinning Machines, of which the following is a specification. A

This invention relates to the spindles of spinning machines and more particularly" to improvements inmachines of the well known ring spinning type. In such machines, the thread or yarn is fed from rollers through a guide ring to the traveller which rotates on a ring carried by the ring frame round the cop or bobbin on which the thread is to be wound. In such machines twisting is obtained by the rotation of the traveller and the winding by the slight lag of the traveller relatively to the bobbin;.the tension of the thread varies, being greatest when it is being wound on an empty bobbin or a bobbin of small diameter, and least when the thread is being wound, on a full bobbin of large diameter. The speed of such a machine is limited as, at very high speeds, the tension on the threadbecomes so great that the thread is liable to break and in view of this it is practically impossible to spin very fine threads. y

The object of this invention is to improve this type of machine so as to permit of a higher speed of twisting and winding being used with less liability of breakage, so

that very fine counts may be .used, the ten sion of thethread being automatically regulated so as to be kept practically constant irrespective of the'diameter of the bobbin on which it is being wound. I

The present invention consists in making the spindle integral throughout and, in mounting it in special bearings soas to permit of its being run at very much higher speeds than has hitherto been possible, for example at speeds of twenty thousand revo lutions, per minute or higher. The invention further consists in a novel metliodof mounting thebobbin on the spindle so that it is capable of relative motion thereto,

In the accompanying drawings Fig. 1 illustrates in sectional elevation one, method of carrying this invention into effect, and

Fig. 2 shows an alternative form of bearing for the spindle. In this drawing a represents a spindle tothe upper end of which 1922. Serial No. 567,722.

is secured funnel or cap b. The upper end of the spindle is provided with a central aperture 0 from the lower end of whichone or more outwardly extending holes 03 are formed, the lower end of these holes being in communication with the interior of funnel- Z), The spindle ais provided at'its upper and lower ends with bearings, the upper one of which consists of a ball bearing orother suitable form of bearing the in -ner race 6 of which fits on the spindle while the outer race f is contained in acup shaped member 9 provided with a flange by means of which it is secured to the stationary plate It. The outer race 7 fits loosely into the interior of the member *9 and is surrounded by a tubular washer is of felt, rubber or other compressible material. The upper edge of racef engages the interior of the member 9 and is held in frictional engagement'therewith by means" of a compressible washer or sprin Z held inengage ment with the lower edge of the race by means ofa second cup-shaped member m screwed on to memberg. The washer Z is preferably providedwith a metal bearing surface a on its upper or upper and lower sides. The bearing illustrated at the lower end of the spindleissubstantially the same as thatjustzdescribed except that; in this case the lower edge ofthe race f" engages with an annular member 0. which isv fo rced'upwards by means of a spring p so as to cause the upperedge of the race 7 to frictionally engage the interior of the cup-shaped mem-" The spindle is driven bymeans of her, 9. p a belt passing around a grooved pulley q formed integral with or securedto the'ca'p Z). lVith bearingshsuch as described the.

spindle may be run at very higlrspeeds as, if oscillations are set up owingvto the p high speed the; bearings permit offthespinw ,dlemoving laterally and taking up a new position the movement being opposed by the friction of the edges ofthe ballraces which clamps out the oscillation andpreventsjany tendency for are continue or increase. a Fig. 2 shows an alternative form of bean .ingfor the spindle to that shown in 1." a p In this case the spindle a is surrounded by a bush orsleeve'of graphite 10 provided with a flange 11 at its upper end which is held in engagement with the interior of the member 9 by means of a spring 9'"; The flange" llis capable of lateral movement but as de i scribed in connection with the bearings illustrated in Fig. 1 this lateral movement is accompanied by considerable friction between the flange and the member g which tends to damp out any oscillation of the spindle causing the movement. Bearings such illustrated in Fig. 2 may be us:d either at the upper or lower end of the spindle in place of those illustrated in Fig. 1.

In order. to admit of relative movement of the spindle and the bobbin which is mounted upon it I provide a sleeve 1" which surrounds the spindle a and is feathered thereon so as to be capable of longitudinal movement .while running in synchronism therewith. This sleeve is provided with a flange 8 at its upper end which is frictionally held between an annular ring t and a flange a formed on a sleeve '0 which loosely surrounds the spindle a. In some-circumstances either nor 6 may be slightly springy. A paper or other spool or quill w on which the thread is woundis fitted on the sleeve 0; which is made slightly tapered in order to hold it firmly. As shown the quill w is loose around the spindle a. The quill and spindle will tend to run in synchronism but means are provided whereby the quill 'w and sleeve '0 run at a. slightly different speed from the spindle (a to cause winding of the yarn on the quill. Secured tothe lower end of sleeve 1- is the inner race 2 of a ball or other suitable bearing, the outer race 3 of which is held between a plate 41. and an annular washer 5 which are resiliently secured to gether by means of spring surrounded studs 6. An annular space 7 is provided around the race 3 so that the bearing is. free to move laterally should oscillation of the sprindle occur thus allowing it to take up a new position when the position of the spindle bearing alters. Thi'slateral movement however is opposed by the friction between race 3 and plate 4%, and washer 5 which as sists in damping out the oscillation. Vertical rec procating movement 18 transmitted to the sleeve o by means of the traverse frame Swhich is secured to the plate 4 in any convenient manner. This reciprocating motion .allows of the thread being wound evenly on the quill. The slip between the. sleeve 0 and the spindle may be controlled in any suitable manner, for example the tension of the thread may be caused to apply a brake either mechanically or electrically to the surface or periphery of the annular ring t.

The operation is as follows :-The thread is fed from the draft rollers through a ring which is mounted substantially vertically above the aperture cl. It then passes down into the interior of the funnel b and from the lower edge through a suitable eye 9 on to they quill on which it is wound by the retardation of the sleeve 1). The ring through which the thread passes before entering the funnel is preferably mounted on a pivoted lever which operates the mechanism for applying the braking effect on the annular ring t and sleeve '0.

It is to be understood that although the bearings described above are particularly suitable for spindles of spinning and the like machines they are not limited to this use as they are equally applicable to all types of spindles which are required to run at very high speeds.
